ok so i have an audi a8 with 80,000 miles rear brake pads were gone so i took the caliper off and couldnt compress them so i went online and it said to use vagcom so i do that but first i enabled the brakes than disable them with the switch to find out the capiper is sticking out all the way i cant get it back in help what do i do the car is sitting in the driveway all apart cant move it or anything!

 

Yes you need a vag com, the parking brake is electronic, so it has to be electronically retracted.

 

the promblem is i took the caliper off and extended it and the piston came out

 

LOL, good luck getting that back in...... Seriously, that was a bad mistake, its close to impossible to get those back in on an A8. If you can't get it back in, you may have to buy a new caliper assembly.

 

Got it back in and works great

 

You lucked out there, glad you got it back in.

 

Heh.. I've done that before, sucks

 

yeah not fun at all!
